UPDATE: Thanks to "alabamaargiope from Madison, AL USA" for pointing out that it is indeed the charger that's the problem here. The batteries do infact recharge fine if I leave them in my "dumb" recharger for two "sessions", ie for a total of 30hrs. It would have been useful if Lenmar had addressed this problem on their packaging rather than letting us find out afterwards that we should really upgrade our charger to a more "intelligent" unit before buying these batteries.

ORIGINAL REVIEW: These Lenmar NiMH rechargeable AA batteries are rated at 2000mAh, which means a higher current than from most other rechargeables available, which is why I bought them. However, using an Energizer ACCU recharger that automatically times out after 15hrs, these batteries last only half as long as other NiMH batteries I use, even though these other batteries don't look nearly as good on paper as the Lenmar brand (namely Energizer rated 1600mAh, Energizer rated 1850mAh and Kodak rated 1850mAh). So I am not sure if these Lenmar batteries are just no good, or if I should be using a more sophisticated recharger (perhaps one sold by Lenmar), but I'm going to avoid this brand in the future. Why buy batteries that cannot be fully recharged by any NiMH recharger?

This battery is pretty good. It lasts longer than I expected for 10 bucks. To me, I see nothing different between this $10 Lenmar and $25 Kodak.

I owned four different sets of NiMH AAs; this was the latest purchase and the first one to stop working. I do have decent chargers and never dropped them or anything. It actually ruined my day twice. Very disappointed.

I purchased two ten packs of Lenmar batteries. Of the twenty batteries, only 4 would take a charge. I used 3 different chargers, an Energizer, LaCrosse, and a RipVan100. The LaCrosse is a high-end charger with diagnostics (can display voltage levels, etc., individually for each battery, it can also 'repair' batteries maximum capacities, etc. - so can the RipVan100)... None could charge the 16 faulty batteries. I sent both 10 packs back.

I was tempted by the cheap price and got myself a 10 pack. They are rated at 2000 mAh, but run out of juice after the digital camera has shot maybe 5 frames. My 2 year old Panasonic 1600 mAh in contrast can run the same camera for over a 100 shots. I tried these batteries in my MP3 player - and even there, it won't supply enough juice after an hr worth of playback. It is not that the battery does not hold any charge - that it has. But it just does not supply the peak current required by most digital devices. It seems to be all right for use in a flashlight. A set of batteries that will not power a camera will power a flashlight (a bit dimly) for hours (yeah - I tested it). For the test, I had charged the panasonics and the lenmars for the same duration (it is not a charger issue).

I plan to complain to the state consumer affairs department regarding this brand and hope action is taken against shady products which are nothing but rip-offs.

One last tip - nowadays, the best NiMH batteries are made by Sanyo. It is better to pay 2 - 4 times for them than for a Lenmar. Trust me!

These charge in any charger that I have used.

All of my Lenmars lasted a long time, longer then the other name brand rechargeable batteries that I have used, and I still have 2 or 3 around that are holding a good charge after nearly 10 years.

I bought 12 of 1000mAh Lenmar rechargeable batteries 2 years ago. They were great initially. However, they become useless soon after the 1-year warranty expired. Now, 9 out of 12 won't even hold a charge even though I only used them for 20 times or less. I won't ever buy another Lenmar battery.

I bought 8 of the 2300 mAh Lenmar batteries about 1-2 years ago. Initially they were great, compared to the 1600 mAh batteries I had been using, but they quickly deteriorated to the point that they just won't hold a charge, and they are all now completely unusable. The 1600 mAh NiMH batteries I bought before these are still going strong. I won't ever buy another Lenmar battery.

These are fine batteries that deliver great bang for the buck, which is true of all high-quality NiMH batteries I've tried. The problem a previous reviewer reports with low capacity is indeed with his charger, not the batteries themselves. The charger he mentions delivers a fixed amount of current per hour for fifteen hours and shuts off. It has no "intelligence" about the capacity of the battery in it, about its current charge state, or anything else. Using these batteries in a good, intelligent charger, such as a Maha MH-C401FS or the smart Lenmar charger he mentions, yields great results, as the charger recognizes the capacity of the battery and doesn't stop charging until it reaches it.

Use these batteries with a good charger and they'll please you over and over again.
